PTFE water valve spring loaded seals

      The Spring energized seal is a sealing device consisting of a PTFE or other polymer, energized by a corrosion resistant metal spring. When the seal is seated in the gland, the spring is under compression applying force on the gland sealing surfaces thereby creating a tight barrier to prevent gas or fluids from leaking. The spring also provides resiliency to compensate for seal wear, gland misalignment or eccentricity. While spring force provides adequate force for sealing at low pressure, at high pressure the system pressure augments the spring force to provide an even tighter seal. PTFE water valve spring loaded sealsare precision machined from PTFE, filled PTFE and other high performance polymers.
